[thatblindgeye]

Follow up to breaking change PR patternfly/patternfly-react#10649

This could probably replace the existing Toolbar rule toolbarItem-warn-update-markup. 10649 completely replaces instances of Chip with Label and will need fixers.

Required actions:

1. Build codemod
2. Build test
3. Update readme with description & example
